  1. 2080 ChaitraChapter 3: DC Generator3.3 EMF Equation

    A 25 kW, 125 V separately excited dc machine is operated at a constant speed of 3000 rpm with a constant field current such that the open circuit armature voltage is 125 V. The armature resistance is 0.02 Ω. Compute the armature current, terminal power, electromagnetic power and torque when the terminal voltage is (i) 128 V (ii) 124 V.

  2. 2078 ChaitraChapter 3: DC Generator3.3 EMF Equation

    A 4 pole shunt generator with a lap wound has armature resistance of 0.1 ohm and field circuit resistance of 50 ohm. The generator supply power to six filament lamps of rated 200 V 600 Watt each. The brush contact drop is 1 V per brush. If generator terminal voltage is 220 V after lamps are connected then find armature current and generated emf.
